TRUCK SIDE FRAME.

Specification of Letters Patent.

Patented May 9, 1916.

Application filed August 12, 1912 Serial No. 714,690.

1 '0 all whom it may concern:

-Chicage, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Truck Side Frames, of which the following is a specification.

This invention relates to improvements in truck side frames, and has for its object to provide an improved side frame capable of use with the type of journal box ordinarily used in present day practice, known as the M. C. B. journal box.

. Another object of this invention is to provide an integral truck frame capable of use with such a journal box.

Still another. object of this invention is the provision of an integral side frame which. may be readily disengaged from or secured to a journal box of the type stated.

A still further object of the invention is to provide improved fastening and locking means for use in securing such side frame to such journal box.

Other objects ill be set forth and made clear in the following specification and accompanying drawing, in which- Figure 1 is a plan view of my improved side frame; Fig. 2 is a side elevation of the same; Fig. 3 is a detailelevation showing one end of my side frame in engagement with the journal box and secured thereto. Fig. 4' is a side elevation of my improved bolting member. Fig. 5 is a side elevation of a locking rod. Fig. 6 is a plan view of the structure shown in Fig. 3; and Fig. 7 is a section. along the line 7-7 of Fig. 2.

Like numerals refer to like elements throughout the drawings.

10 designates my improved truck side frame, formed preferably of a single piece and having ends 11. Projecting from each end are the arm members 12 provided with int-urned extremities 13 forming with the end three sides of a rectangle, as shown in Fig. 2. Adjacent the juncture of the arms 12 with the end 11 the latter is notched or undercut, as shown at 14. The under sides of the arms are also similarly notched or undercut at 15, adjacent the inturned extremities 13.

Apertures 16 are provided through the arms adjacent their juncture with the end 11, and a groove 17 is provided in the outer portion of said end, said apertures arid groove being in alinement, as shown in Fig.

7 Apertures 18 are provided extending through the arms 12, adjacent'their outer ends, and the tips of the inturned extremities 13 are slightly grooved, as indicated at 19 in Fig. 2. These grooves and'apertures are also in alinement for a purpose to be hereinafter described.

In Fig. 3 I have shown an M. C. B. journal box 20, of conventional design having the usual lugs 21 formed at each edge. Extending through these lugs are the apertures 21, in alinement with grooves 22 formed in the sides of the journal box. When in assembled relation, as indicated in Fig. 3, the arms 12 of the side frame are adapted to fit over the journal box, the lugs 21 of the latter being seated in notches 14 and 15 of the side frame. When in proper position the apertures 16 and grooves 17 will form with one pair of apertures 21 and one groove 22 a continuous aperture, as will be apparent from an examination of Fig. 3. Similarly, the apertures 18 and grooves 19 of the side frame will aline with the other pair of apertures 21 and groove 22 and form a partially continuous aperture. Extending between the lower apertures 16 and 18 in the side frame I have provided a 1groove 12 for a purpose to be described ater.

sembled relation with respect to the journal box, I have provided the U-shaped bolt member 25, having the arms 26 threaded at their extremities 27-see Fig. 4. The base portion 28 connects the arms 26 of the bolting member. These arms are adapted to extend through the respective continuous apertures mentioned above, as shown in Fig. 3 the base of the bolting member. being seated in the groove 12. It willbe apparent that when the bolting member is in the position shown in Fig. 3, one of the arms 26 will serve as a key seated in the respective groove 22 of the journal box and the groove 17 in the end of the side frame. keying effect will also be present between the grooves at the extremities 13 of the arms 12 and the grooves 22 in the side of the journal box. Besides this keying effect of the bolting member, the latter also serves as a true bolt, since it projects through the apertures 16 and 18 of the truck frame and the apertures 21 of the journal box. The threaded extremities 27 of the bolt member A slight .nut 31 is also provided with apertures 33 extending therethrough and adapted to aline with the apertures 32 inthe nut 30. The nuts 30 and 31 are provided with respective seating flanges 30 and 31'. The aperture 32in the nut 30 is threaded, whereas the aperture 33 in the nut 31 is not necessarily threaded.

A locking rod 35shown in Fig. 5is provided at one extremity, with. the enlarged threaded portion 36, of a size adapted to threadably engage the threaded aperture 32 cf the nut 30. The opposite end 37 of the locking rod is of slightly smaller diportion 38 is located intermediate the ends of the rod 35. The aperture in the nut 31 is ofa diameter approximately equal to that of the end 37 of the rodu35.

Theopurpose of the locking rod is as follows: When the nuts 30 and 31 are screwed into the position shown in Fig. 3, and the apertures 32 and 33 are mutually al-ined, the end 27 and main portion of the locking rod may be passed through the aperture 32 in thenut 30. Upon rotation of the rod 35, the threaded end 36 thereof will engage with the threaded aperture 32 and be drawn into locking position, the end-37 of said rod entering the aperture 33 in the nut 31. It will be apparent that when the extremities 36 and 37 of the rod 35 are in the position shown in Fig. 3, unscrewing of the nuts 30 and 31 from the threaded extremities 27 of the Ll-shaped bolt 35 will be prevented. The square portion 38 of the rod 35 may be engaged by a wrench, etc., to rotate said rod as desired.

It will be seen from the above descrip- I tion and the accompanying drawings that I have provided an improved integral side frame capable of use with the conventional form of journal box, and also capable of ready. engagement and disengagement therewith. It will be furtherobserved that the journal boxes are positively locked in true alinement with the side frames by reason of the rodsserving as keys and projecting into vertical grooves in the opposite sides of the journal box and into registering grooves in adjacent portions of the side frame, consequently the journal bearings are retained in planes transverse to the side frame, so as to accurately aline with the axle journals. It will be further apparent that have provided an improved securing and locking means for use in connection therewith, although I do not wish to restrict myself to the use of said engaging and locking means with the specific form of side frame shown. Furthermore, I do not wish to be restricted to the exact form. shown in the drawings and described in the specification beyond the scope of the appended claims.
